Re: LF: Re: New QRPPP test to night on WSPR 2 MF

Hi Luis,

Your MF WSPR transmissions are most apprechiated. I like to read about your progress and i'm looking forward to a first decode!
RX is running. TX is running in 20% ratio, also leaving a trace for the other EA stns.
There are a few more EA stns receiving. Some are very close to you. Are they from your local radio club?
What is the current output power? I don't know much about the Ultimate-3. Guess it is not above 2.5W, so the 25W PA will at least improve your signal by another 10 dB.
Maybe it will become an active WSPR evening/night? QRN is extreme here though.

73, Stefan

Vey nice test Andy. Thank you for sharing your results

 

I'm also transmitting QRPPP (may be with one more "P") with just the Ultimate-3 connected to antenna

 

Have been using a vertical 11m high without coil. But last week I finally installed a 70m perimeter loop

and managed to get it tuned to 477KHz. On my monitor at 7Km I have imporved by 10dB with the loop

 

I'm transmitting WSPR-2 and Opera8. So far have got my first (and only) WSPR report from about 500Km

at David EA1FAQ. And last night got a few decodes from Iban EB3FRN

 

I don´t know which is my ERP. But can be probably well under 1mW  ??

 

Next step is an small 25W PA. But for the moment will keep on QRPPP

Congratulations. QRPPP is certainly fun and a real challenge for the RX stations.

Muchas gracias Iban.

 

last 3 nights I tested 20, 1 and 0.1 milliwatt ERP. Here the results :

 

Date night	ERP mW	Total Spots received me	Total stations received me	Max QRB km
April 24 / 25	20	370	21	1284
April 25 / 26	1	45	9	730
April 26 / 27	0,1	19	5	587

 

To night, I’ll be QRV with 0,05 Watts ( 50 micro Watt).

 

Best 73 to all.

HI all.

 

Last night, I tested WSPR 2 MF using 1 milli Watt ERP transmission : 1 Watt output TX, 12 dB attenuator and – 18 dB antenna efficiency.

 

Thanks to the 8 differents stations reports :

 

 

To night, same test but using a 22 dB attenuator instead of the 12 db. The ERP be around 0.1 milli Watt (100 micro Watt). A new challenge.

 

I hope some reports coming from 2200 to 0400 TU...

 

73 to all.
